I have a brand new Hero 3 Black Edition. The battery has no use of WiFi on the remote control or mobile app maintained for one hour not even. only 50 images and three short videos (less than 30 seconds) and the battery was empty. If you take the battery size and the underlying mah 1050 takes real armseelig what was produced there. any smartphone battery has 1700 mAh and is just half as thick. Here needs to be urgently improved. And not only in the next series but even for current model !!!!
